Calibration, sampling & accessories are essential for ensuring the accuracy, reliability and longevity of gas analysis and environmental monitoring systems. Accurate measurements depend on properly calibrated analyzers and correctly designed sampling systems, which is why we offer a complete range of supporting equipment alongside our analyzers and monitors. Our portfolio includes dynamic dilution calibrators that generate precise calibration gas mixtures, flow measurement and control devices for accurate gas handling, and sampling probes, filters and fittings that ensure representative samples reach the analyzer in optimal condition. These products are designed to improve measurement accuracy, reduce maintenance, extend instrument life and simplify field and laboratory operation. Dynamic dilution calibrators produce traceable gas concentrations for calibrating analyzers across their measurement ranges, supporting compliance with quality‑assurance programs. Sampling probes and conditioning systems protect analyzers from dust, moisture and corrosive gases, ensuring reliable performance in harsh environments. Our technical team learns about project measurement goals and working‑site conditions to recommend matched calibration, sampling and accessory combinations. All accessories pass strict pre‑shipment quality inspection. We provide application guidance in documentation, operation guidance, spare‑part options and long‑term remote technical consultation. For calibration laboratories, environmental monitoring networks, industrial plants and service providers, our calibration, sampling & accessories deliver the reliability and engineering quality needed to keep measurement systems accurate and dependable.
